Publication number: 20040242513Abstract: Splice variants of a human “TUB” antisense gene have been discovered, which overlap with human TUB and murine “tub” in antisense orientation. The overlapping portions suggest a regulatory/attenuation effect, due to RNA-RNA-interaction. These findings demonstrate that these TUB antisense constructs can regulate weight disorders, such as obesity, and progressive sensorineural degeneration phenotypes of the central nervous system. Accordingly, the invention provides therapeutic methods utilizing these constructs, as well as methods for identifying compounds that can therapeutically treat weight disorders.Type: ApplicationFiled: May 7, 2004Publication date: December 2, 2004Inventors: Dirk Prawitt, Bernhard Ulrich Zabel, Thomas Brueckmann, Erwin Schmidt, Andreas Winterpacht, Thomas Hankeln

Publication number: 20030176715Abstract: Aromatic hydrocarbons are partially oxidized in the gas phase over a catalyst at elevated temperature to form carboxylic acids or carboxylic anhydrides in a process in which a gas stream laden with the starting materials is passed through a shell-and-tube reactor whose temperature is controlled by means of one or more separate thermostatting baths conveyed in countercurrent to the starting gas stream, wherein the difference between the temperature of the thermostatting bath in the region of the reactor outlet and the temperature of the product gas stream leaving the reactor is employed to control the selectivity of the gas-phase oxidation.Type: ApplicationFiled: February 12, 2003Publication date: September 18, 2003Inventors: Peter Reuter, Bernhard Ulrich, Thomas Heidemann

Publication number: 20030013931Abstract: A process and an apparatus for producing a homogeneous mixture of a gaseous aromatic hydrocarbon and an oxygen-containing gas for catalytic gas-phase reactions, in particular a homogeneous mixture of gaseous o-xylene and/or naphthalene and air for preparing phthalic anhydride, are provided. The liquid aromatic hydrocarbon is atomized to form droplets having a diameter of less than 1 mm and injected into an oxygen-containing gas stream (12) preheated to above the boiling point of the aromatic hydrocarbon. According to the invention, the liquid aromatic hydrocarbon is atomized by means of nozzles (15) which form a hollow cone (16), preferably by means of swirl nozzles. The o-xylene/air mixture is advantageously produced in a chamber which is bounded by side walls (18) heated to above the boiling point of the hydrocarbon.Type: ApplicationFiled: June 24, 2002Publication date: January 16, 2003Inventors: Ulrich Block, Rolf Seubert, Bernhard Ulrich, Helmut Wunschmann

Patent number: 6288273Abstract: The invention relates to a method for producing gas-phase catalysts gas-phase oxidation of aromatic hydrocarbons into carboxylic acids and/or carboxylic acid anhydrides upon whose carrier material a coating containing catalytically active metal oxide is applied in the form of a shell, wherein a powder is initially produced from a solution and/or suspension of catalytically active metal oxides and the precursor compounds thereof or simply the precursor compounds in the presence or absence of auxiliary agents in order to produce the catalyst. Said powder is then applied, in the form of a shell, to the carrier in the presence or absence of auxiliary agents after or without previous conditioning and without previous thermal treatment to produce the catalyst. The carrier which is thus coated undergoes thermal treatment in order to produce catalytically active metal oxides.Type: GrantFiled: August 26, 1999Date of Patent: September 11, 2001Assignee: BASF AktiengesellschaftInventors: Thomas Heidemann, Thomas Cimniak, Bernhard Ulrich

Patent number: 4445513Abstract: A device for straightening a spinal column having a succession of vertebrae extending along a nonstraight line lying generally in a plane has an elongated bar lying generally in the plane of the line and having a pair of relatively longitudinally displaceable bar parts in turn having respective bar ends. A pair of connectors of the bar ends are secured to respective vertebrae of the succession. Respective pivots between the connectors and the respective ends define therebetween respective generally parallel axes transverse to the plane. A main abutment movable along and flexible on one of the parts and longitudinally engageable with the other of the parts serves for limiting relative longitudinal displacement of the parts toward each other. Thus the main abutment can be moved along the one part to increase the spacing between the ends and thereby can straighten the succession of vertebrae between the connectors.Type: GrantFiled: May 28, 1982Date of Patent: May 1, 1984Assignee: Max Bernhard UlrichInventors: Bernhard Ulrich, Gys H. Slot

Patent number: 4101985Abstract: A hip-joint prosthesis has a ball head shaped to fit in an acetabulum, an elongated shaft adapted to fit in and between two opposite sides of a medullary cavity of a femur, and a stem between and connecting the head to one end of the shaft. This shaft is curved in a plane and has a concave longitudinal edge and a convex longitudinal edge. A laterally projecting shoulder between the stem and the shank is engageable against a sawed-off end of a femur in whose medullary cavity the shaft is engaged. The shaft is formed on its concave edge at its two ends with inner and outer engagement surfaces of planar shape. Between these engagement surfaces on the convex side there is formed an intermediate engagement surface. When mounted in a femur the inner and outer engagement surfaces engage against one side of the medullary cavity and the intermediate engagement surface against the other for firm mounting of the shaft in the femur.Type: GrantFiled: March 18, 1977Date of Patent: July 25, 1978Inventors: Friedrich Baumann, Max Bernhard Ulrich

Patent number: 4047765Abstract: A hydraulic braking system is provided for automatically apportioning braking of the wheels of a vehicle in accordance with the load on respective wheels. A plurality of brake control assemblies each dedicated to one of the wheels of the vehicle are coupled to produce braking of the corresponding wheel upon activation of the brake pedal. The degree of actuation of each brake control assembly is controlled by an element which senses load differences between all wheels on the vehicle (including load differences between wheels on either side of the vehicle and between front and rear wheels), and adjusts the degree of actuation of the corresponding brake control assembly accordingly. In an illustrative embodiment each brake control assembly includes a brake control cylinder having a piston movably disposed therein. The pistons are coupled to the brake pedal so as to be maximally advanced into the brake control cylinder when a maximum brake force is applied.Type: GrantFiled: March 29, 1976Date of Patent: September 13, 1977Assignee: Tex-Trans, Inc.Inventor: Bernhard Ulrich, Jr.

Patent number: 3966365Abstract: A hydraulic power transmission and braking system for vehicles in which individual hydraulic wheel motors are connected through suitable control apparatus to a variable displacement hydraulic pump which is driven by an appropriate power source. The displacement of the pump varies automatically in response to hydraulic fluid pressure and flow rate requirements imposed by the vehicle operating conditions. The power transmission control apparatus automatically switches from the 4-wheel drive mode to the 2-wheel drive mode as the vehicle accelerates past a predetermined speed. The braking control system proportions the braking force applied to each of the hydraulic wheel motors in accordance with the load imposed on that wheel by the vehicle operating conditions.Type: GrantFiled: July 3, 1974Date of Patent: June 29, 1976Assignee: Tex Trans Inc.Inventor: Bernhard Ulrich, Jr.
